Abstract
An automatic leveling device and a method for a variable-slope obliquely-running container, the device comprises: a box body (1), a movable bottom plate (2), an automatic leveling assembly (3) and a pulley (4) or a backpack carrier (5), and accommodates the automatic leveling of the variable-slope obliquely-running container under various working conditions by changing the angle of a lifting platform (4-1) on the pulley (4) or the backpack carrier (5). When the obliquely-running container runs on a variable-slope guide rail section, a position-pose sensor (1-1) monitors the angle variation of the box body (1) and transmits a signal to an automatic leveling control system, which analyzes the signal and controls the movement of a servo motor (3-12), and the automatic leveling assembly (3) compensates by action the angle variation of the box body (1) so that the box body (1) can always be kept in a horizontal state, thereby enabling the obliquely-running container to run on a variable-slope rail.
Description
AUTOMATIC LEVELING DEVICE AND METHOD FOR VARIABLE-SLOPE OBLIQUELY-RUNNING CONTAINER
Field of the Invention
The present invention relates to the elevator field, in particular to an automatic leveling device for a variable-slope obliquely running container and method thereof, which are especially applicable to obliquely running containers that are operated at a variable slope or along a variable track under the influence of the operating conditions in mine roadways or the shapes of buildings.
Background of the Invention
As high-rise buildings emerge continuously, the importance and advantages of elevators, which are used as a convenient and quick vertical transportation means, become more and more apparent. As elevator techniques are developed rapidly, special elevators applied in different environments and locations facilitate people's lives. A demand for obliquely running containers has been raised, in order to provide a convenient transportation means in mine roadways, tourist spots, buildings on hillsides or mountaintop, regions where the residential buildings are built on hillsides owing to land shortage in the urban area, complex underground roadways and vertical transportation of maintenance personnel and goods below the rated load. Most existing obliquely running containers are obliquely running containers that always run at a fixed slope along linear tracks. However, sometimes it is difficult to arrange a fixed-slope running track for an obliquely running container, owing to the influence of the shapes of special buildings or the operating conditions in roadways.
In a case that an obliquely running container has to run along a variable-slope track, the car of the container must be level in real time, to ensure comfortability of the passengers in the container. Existing car levelling mechanisms usually employ hydraulic cylinders for leveling. resulting in the following drawbacks: 1. a hydraulic power source (hydraulic pump station) is required, which occupies a large space and is cumbersome; 2. the real-time leveling effect is poor, because the hydraulic system has a hysteresis characteristic; 3. the hydraulic cylinders have a poor transition effect in continuous micro-regulation (an arc section operating), and are difficult to control by means of small flow rate changes; 4. the system has a higher requirement for pressure maintaining in the hydraulic cylinders, and hydraulic leakage and car instability may occur if the system is kept in a stop state for a long time.
